If you’re considering of buying a dehumidifier, you might be questioning, ‘how do dehumidifiers work?’ While the finest humidifiers add moisture to the air when it’s too dry, dehumidifiers take away moisture from the air when it’s too humid, making these little beauties nice in the event you dwell in a sizzling local weather or simply need a extra comfy residing setting in the course of the spring and summer season.
We’ve all skilled humidity of a point or one other. That weighted feeling within the air normally comes from warmth, rain or fog and may actually have an effect on how we really feel as we go concerning the day. When this occurs, it will possibly really feel stuffy and even scent like should, which may carry on a sequence of points for each you and your house. This is the place utilizing a very good dehumidifier is available in, and it’s worthwhile to find out about and discover how a dehumidifier can profit you.
In this text, we’ll focus on what dehumidifiers are and reply a standard query, how do dehumidifiers work? We’ll go over the advantages of utilizing a dehumidifier and, lastly, we’ll additionally present an concept of how a lot power it takes to run these models and what which may price you.
How do dehumidifiers work?
According to the National Asthma Council, dehumidifiers change a room’s humidity stage to a relative humidity of 30-50% by taking extra moisture out of the air. When this occurs, mildew, mud mites, and different allergens are much less prone to survive.
A dehumidistat detects the moisture stage within the air and powers the unit on when vital.
Refrigerant-based dehumidifiers are the most well-liked fashion of dehumidifiers. They are sometimes made up of 4 elements:
- Fan compressor that expands and contracts a refrigerant fuel (like freon) to chill down the coils
- Reheater that collects warmth generated by the cooling course of
- Refrigerated or cooled coils that take moisture from the air by condensation
- Collection tank or tray that collects moisture from the cooled coils
Like a vacuum utilizing a fan, dehumidifiers cross air over their refrigerated coils. This course of is just like how an air con unit works and makes the moisture condense on the unit’s coils. The heat air contracts and loses the moisture it will possibly not maintain because it strikes by the cool coils. This is when it creates condensation, which accumulates contained in the dehumidifier’s storage tank or tray.Then, by its different facet, the dehumidifier sends the air again into the room over a heat coil.
Do dehumidifiers actually work?
Dehumidifiers can supply the next advantages:
- Air high quality enchancment with lowered humidity
- Mold prevention
- Dust elimination
- Personal consolation
- Lower power prices
- Protection of your house
For these of you questioning ‘do dehumidifiers help with allergies?’, the reply is sure. By lowering the humidity in your house, it’s also possible to assist to cut back bronchial asthma signs and irritation. If you’re going to put money into a dehumidifier, you need to ensure you’re getting the entire advantages that it has to supply. The excellent news is there’s a strategy to know whether or not a dehumidifier is basically working for you.
Measuring a dehumidifier’s effectiveness
According to the Code of Federal Regulations of the United States of America, there are two issues that point out how properly a dehumidifier is working and functioning.
- Efficiency. You’ll must assess how environment friendly a dehumidifier is (its “energy factor”) to know the way properly it’s working for you. Find this by dividing the quantity of water it removes by how a lot energy it consumes. This worth is measured in liters or pints per kilowatt-hour (L/kWh).
- Water eliminated per day. The quantity of water a dehumidifier removes in a steady 24-hour interval of use (in liters or pints) clearly signifies how properly the unit is working. Larger dehumidifiers, after all, take away extra water than their smaller counterparts.
Wattage can also be vital to think about. Though it gained’t point out the standard of a dehumidifier, larger wattage sometimes means it really works more durable and removes extra water every hour. For instance:
- A small table-top unit takes about 20 watts to function, takes away about 0.25 liters of water a day, and has a tank that holds about 500 ml.
- A big dehumidifier removes about 50 liters of water a day and makes use of 1,000 watts or so.
However, you might want to contemplate these figures collectively after which evaluate the 2 models to evaluate their advantage – the wattage by itself can’t offer you that.
The small unit will take about 4 days to take away one liter or 200 days to take away 50 liters, which can use about 96kWh (200 days x 24 hours x 0.02 kW). The massive unit will take about someday to take away 50 liters, which can use about 24kWh. So, on this instance, the big unit is 4 occasions extra environment friendly and 200 occasions quicker than its small counterpart.
Finding the suitable dehumidifier
As with any sort of product, some dehumidifiers work properly and do what they are saying they are going to do, whereas some go away so much to be desired. There are some key issues you are able to do when buying round for a dehumidifier.

This approach, you may probably take them residence, attempt them out to see in the event that they do what they declare to and, if not, return them.
Finally, search for and assess credible opinions, whereas paying shut consideration to what customers say concerning the options most vital to you.
Do dehumidifiers use a whole lot of electrical energy?
With the entire advantages dehumidifiers supply, power effectivity shouldn’t be certainly one of them. While they don’t take up as a lot power as an air con unit which could possibly be 300 kWh month-to-month, they do eat greater than an ordinary fridge. Of course, like every equipment, the quantity of power a dehumidifier requires will range by sort, measurement and mannequin. They common out at round 280 watts (to check, computer systems sometimes use about 360 watts).
To save power consumption and cash in your invoice every month, take a look at dehumidifier fashions that meet or exceed the Energy Star necessities. The larger a mannequin’s Energy Factor (EF) quantity is, the extra water it removes per kWh of electrical energy it consumes. And, the bigger the unit, the extra influence on power use and price a higher-efficiency score may have.
Here’s an instance from Learn Metrics of how a lot it might price you to run an energy-efficient (EF of two.0) vs. energy-inefficient (EF of 1.0) dehumidifier in your house. In this case, assume a value of 13 cents per kWh, with each models holding 70 pints and working for 1,000 hours. The environment friendly EF 2.0 unit would price about $90 per yr to run, whereas the inefficient EF 1.0 unit would price about twice as a lot.
Making certain you clear and correctly keep your dehumidifier also can allow you to save on power prices. Check out our information for how you can clear a dehumidifier for extra data. And, in the event you’re hoping to avoid wasting power prices general, there’s a good facet impact of utilizing a dehumidifier at residence: you would possibly really feel cooler and, in flip, scale back your power consumption and prices.
